1. Uma análise comparativa do desempenho de quatro sistemas de umidificação do ar em condições de seca no centro-oeste brasileiro
Resumo Quatro sistemas de umidificação do ar foram examinados e seus desempenhos comparados sob condições de seca do centro-oeste brasileiro. Esses sistemas são umidificador elétrico, bacia com água, toalha úmida e um sistema artesanal feito com telhas cerâmicas especialmente para este trabalho. A avaliação foi realizada entre julho e outubro de 2

2. Effects of herd management practices on somatic cell counts in an arid climate
The objective of this study was to evaluate associations between average lactation somatic cell counts (SCC) and herd management practices in an arid climate. A total of 38,530 average lactation SCC records for 10,216 Holstein cows gathered on 25 dairy farms from January 2009 to October 2012 in Isfahan (Iran) were analyzed. Average lactation SCC (cells × 1,

3. Effect of heat and moisture exchangers on the prevention of ventilator-associated pneumonia in critically ill patients
Ventilator-associated pneumonia (VAP) remains one of the major causes of infection in the intensive care unit (ICU) and is associated with the length of hospital stay, duration of mechanical ventilation, and use of broad-spectrum antibiotics. We compared the frequency of VAP 10 months prior to (pre-intervention group) and 13 months after (post-intervention g

4. Dimensionamento de um umidificador para células a combustível em aplicações móveis / Design of a Humidifier for Fuel Cells in Mobile Applications.
Células a combustível geram energia a partir de um processo eletroquímico decorrente de uma reação química, com a presença de átomos de hidrogênio e oxigênio, ocorrendo à liberação de prótons de hidrogênio (H+) e de elétrons de oxigênio (O2-), para obtenção de energia elétrica, calor (produtos) e água (subproduto). Dentre os modelos de m

5. Simulação de sistemas de climatização combinada à simulação higrotérmica de edificações
Due to the nonexistence of a building simulation program that can simulate in details the combined heat, vapor and liquid transfer in porous elements and the HVAC systems, a generic and flexible computational algorithm has been elaborated in order to integrate models for both HVAC systems and multizone building models. In that algorithm, mathematical models

6. Resfriamento evaporativo e condicionamento de ar convencional: estudo experimental comparativo / Evaporative cooling and conventional air conditioning: a comparative experimental study
This experimental research aims to compare the evaporative cooling with the conventional air conditioning in terms of levels of humidity, reduction in indoor air temperature, and energy consume. The experiment was conducted in three purpose-built test cells, similar in structure, which were exposed to the same climatic conditions and showed the same indoor a

7. O faturamento gerado pelos procedimentos de enfermagem em uma unidade de terapia intensiva. / Turnover generated by nursing procedures at a intensive care unit.
Every country, no matter the health assistance model adopted, has been sharing a common problem: high costs facing limited resources and budgets. Thus, growing and high costs of health services have been affecting all public or private service providers. In the current financial health reality, hospitals will have to adopt a system to get a better control of

8. Microbial prevalence in domestic humidifiers.
The prevalence of viable thermophilic bacteria and actinomycetes and mesophilic fungi was examined in 145 samples from 110 domestic humidifiers. A total of 72 and 43% of furnace and console humidifier samples, respectively, contained viable thermophilic bacteria, whereas 60 and 72% of these samples produced mesophilic fungal growth. Thermophilic actinomycete

9. Extrinsic allergic alveolitis caused by a cold water humidifier.
Three workers developed classical extrinsic allergic alveolitis while working in a printing works that had a contaminated cold water humidifier. All had nodular shadows on their chest radiographs, reduced gas transfer measurements, and lung biopsy specimens that showed an alveolitis with giant cells and cholesterol clefts. In two subjects bronchoalveolar lav

10. An investigation of operating theatre staff exposed to humidifier fever antigens.
Sixty staff working in a hospital operating theatre, where a case of humidifier fever had been identified, were studied together with 49 subjects working in other parts of the hospital. They each had a blood test for serology, a skin test, and a chest radiograph and completed a questionnaire. The theatre staff also had pulmonary function tests. The theatre h

11. Climate, intermittent humidification, and humidifier fever.
Two summer outbreaks of humidifier fever (HF) are described in a microprocessor factory (factory A) and a printing factory (factory B). The air in each factory was humidified intermittently and controlled by present humidistats operating to maintain a relative humidity of 45% by an air handler incorporating a spray humidifier in factory A and two ceiling mou

12. Bacterial colonisation of humidifier attachments on oxygen concentrators prescribed for long term oxygen therapy: a district review.
A microbiological survey was undertaken on the eight patients in the Liverpool District who have a humidifier attachment on their oxygen concentrator. All but one of the humidifiers were contaminated with potentially pathogenic bacteria.
